Same‑sex marriages remain a small share

Even where same‑sex marriage is legal, such unions account for a small fraction of total marriages each year — Pew’s analysis of 2020–2022 data finds they are generally under 4% of marriages, with country variation (e.g., Spain 3.4% in 2021; Ecuador 0.4%). This shows legalization changes legal status and rights but does not, by itself, produce large shifts in the overall marriage composition. — Policymakers and demographers should note that legal recognition expands rights and visibility without necessarily causing major demographic upheaval in marriage rates, which affects forecasts and arguments about social change.
